Today, it also
announced that Yammer will integrate with Microsoft's CRM
product, Dynamics. Whenever an update happens in Dynamics, such
as a sales rep closing a new deal, that info can be automatically
posted on the Yammer ticker stream for all employees to see.

Yammer is like Facebook for enterprises. It's a closed system
so only employees can see the updates.

There's no question, Yammer is one of the companies teaching
enterprises how to integrate social communication into employees'
work day. Salesforce.com is hoping to own that role.
Yammer integrates with Salesforce, too, but Salesforce would
prefer to sell its own version, called Chatter.
